Are you sure that my starting set doesn’t work???
If yes, I think you need more experiments to do...
Fortunately music is an area where creativity always has the upper hand on the cold technique.
Lugia is probably/definitely the most knowledgeable person in these forums. Don't characterize what he said as "aggressive." It wasn't.
You have a collection of modules that makes absolutely no sense on their own. You haven't put the time in studying how analog synths work. You don't just buy a bunch of cool looking stuff and expect to get anywhere. But hey, it's your money and you can waste it however you see fit. You came here looking for answers. He gave them to you for free. Don't squeal because he was curt and to the point.
Now here's my advice. Buy something like a Behringer Neutron. It's $300US. It will teach you everything you need to know about BASIC modular architecture as well as a dedicated line-level out (plus synth level). It has MIDI DIN in as well as USB MIDI. You'll also be able to make use of most of the modules you've already obtained (assuming you have them in a case).
You need a LOT more knowledge before putting together a modular synth that will work for you. Dig in Youtube for tutorials and you may want to download VCV Rack. It's a simulated modular synth environment that is great to learn in.
Respect the knowledge people take the time to share with you. I'm sure you'll have more questions later on and Lugia hitting the reply button rather than skipping it because you got all whiny the last time isn't where you want to be.
